VAX: The VAX acronym is derived from Virtual Address eXtension.
|
|
The VAX computer is designed to use memory addresses beyond
|
|
the hardware's actual limits, enabling it to handle pro-
|
|
grams that are too large to fit into physical memory. The
|
|
VAX computer system is a member of the Digital Equipment
|
|
Corporation (DEC) computer family. Currently the VAX
|
|
series includes models spanning the desktop VAX station to
|
|
mainframe class multi-CPU VAX processors. These vary from
|
|
the superminis, like MicroVAX, to the older, moderate sized
|
|
11/7XX series, to the newer 6000 series. These computer
|
|
systems commonly use an operating system known as VMS.
|
|
|
|
VMS: The VMS acronym is for Virtual Memory System. The operands
|
|
of VMS are very similar to other operating systems. Back
|
|
in the days of stand-alone computer systems, DEC had the
|
|
idea for streamlining the operation of their computers for
|
|
business and engineering. It conceived VMS as a way of
|
|
allowing the basic computer management to be done by a user
|
|
familiar with any of the multiple systems it made.
|
|
|
|
DCL: The DCL acronym is for Digital Command Language. It is the
|
|
fundamental language of the VMS. Those of you who have an
|
|
IBM system, you can think of a DCL program like a batch
|
|
file. You can do a lot with it (much more than a PC-DOS or
|
|
MS-DOS batch) but it work basically the same way. One
|
|
difference is that when you want to execute anything as if
|
|
you were typing it in at the command prompt, you first must
|
|
put a "$" in front of the command in the DCL program. DCL
|
|
programs are commonly called COM files as well. When you
|
|
are not executing a COM or DCL program file, you are almost
|
|
always typing things into the DCL processor.
